Well, the above optimizations didn’t work well on my model 2, but that could be more a function of my TV. I will be trying some various optimizations and see how they look through capture cards.
BUT, stock settings at line4x and line5x look pretty perfect with my saturn and on my TV. I was able to grab some line4x of D&D Shadows over Mystara. Youtube scaled it to 720p, and degrades it a bit, but it’s still not terrible on the eyes. Around 32:33, I cycle through various scanline settings while in one of the shops. The elf/pixie shopkeeper or whatever she is, really shows off the differences, and each setting looks great for whatever your personal taste.
